Dito on Amsoil....
Use it in my '98 Accord. bought the Honda with 190,000 miles on it, now 230,000 with no leaks, smoke etc..
Even my Yamaha C3 scoot (4-stroke)..
Easier starting in cold weather...
Less value train noise (wear) at start up...
MPG is a little bit better...
I also use Amsoil ATF in my Honda automatic, smoothed out the jerky shifts...
I also use synthetic brake fluid as well as the power steering fluid...
Great stuff...
